Description Gordon Sim 2008-06-19 12:03:31 EDT
In the simplest case we should just issue session exceptions when client attempt
to do things that would push the broker above a given limit.
Comment 1 Gordon Sim 2008-07-10 04:47:51 EDT
Moving target to 1.1 as we don't yet have a good solution for this.
Comment 3 Gordon Sim 2008-07-17 11:13:49 EDT
Initial suggested solution is as follows:

On startup broker determines the available system memory. The default policy on
any queue for which an explicit policy is not set is to not go above a certain
percentage of this (else flow to disk or throw exception as usual).
Comment 4 Gordon Sim 2008-07-25 09:36:56 EDT
Fixed by r679462.
Comment 5 Gordon Sim 2008-08-15 04:03:45 EDT
Fix involves applying a fixed size (but configurable) default policy for queues (--default-queue-policy). Once the total message data on the queue reaches that limit, further publications will be either flushed to disk (if the queue is durable) or failed.
Comment 7 Frantisek Reznicek 2008-09-10 04:26:06 EDT
RHTS test MRG_Messaging/qpid_queue_policy_bz452141_bz456667 proves that queue policies (queue max message count and queue byte size) are implemented and tested. (ON_QA->VERIFIED)
